How do I debug a program written in the Go language?

Question

How do I debug a Go program? I have been using the Gedit Go IDE, but it doesn\'t have debugging. Is there a way to step though my code and inspect memory? Or am I stuck with

Answer 1

There is an experimental debugger package called ogle. Not sure how well it works.

Answer 2

GDB 7.5 officially supports Go.

Answer 3

Another debug technique being developed (Q4 2014): Go Execution Tracer

The trace contains

• events related to goroutine scheduling:
  • a goroutine starts executing on a processor,
  • a goroutine blocks on a synchronization primitive,
  • a goroutine creates or unblocks another goroutine;
• network-related events:
  • a goroutine blocks on network IO,
  • a goroutine is unblocked on network IO;
• syscalls-related events:
  • a goroutine enters into syscall,
  • a goroutine returns from syscall;
• garbage-collector-related events:
  • GC start/stop,
  • concurrent sweep start/stop; and
• user events.

By "processor" I mean a logical processor, unit of GOMAXPROCS.
Each event contains event id, a precise timestamp, OS thread id, processor id, goroutine id, stack trace and other relevant information (e.g. unblocked goroutine id).
